Title: Apparatus for loading a ring-spinning machine
IPC: B65H67/06
Filed: 1973-06-27
Abstract: 1423413 Supplying and removing bobbins to and from machines AUGSBURGER KAMMGARN-SPINNEREI AG 27 June 1973 [28 June 1972] 30533/73 Heading DIF In apparatus for loading a ring-spinning machine 1 with supply bobbins in a working position, trolleys 7 loaded with the bobbins 8 (and, subsequently, with empty tubes 10) travel on rollers supported and guided on and by overhead entry 2, creel 3 and exit 4 rails which are linked to a rail system serving the machine. Flexibly coupled entry and exit sections 5 and 6 of creel rail 3 are pneumatically raisable to rails 2 and 4 to form a continuous passage rail therewith as required. In the operation of a conveyor system represented in Fig. 10 and wherein trolleys 7 are mechanically and/or manually moved along the rails thereof, empty tubes 10 are removed at a preliminary machine e.g. a flyer frame 36, from trolleys 7, returned under gravity along a sloping rail section 37b, and replaced by full bobbins 8 which are moved to a lift 38 whereby the trolleys are raised to a sloping feed rail and then run under gravity therealong to reserve rails 42 which may be connected to the feed rail by means of switches 43. At least the same number of trolleys which can be taken up by creel rail 3 is maintained in reserve. In order to replace trolleys carrying tubes 10 on rails 3 by trolleys carrying bobbins 8, the sections 5, 6 are swung upwards to adjoin rails 2. The trolley carrying tubes 10 are then allowed to move towards rails 4 and thereafter roll on rails 42 to a distributing rail 45 and on to rails 2 according to connections effected by switches 44 and 46. When loading and unloading of rails 3 have been completed, sections 5 and 6 are lowered to the positions shown in Fig. 1 and trolleys 7 carrying tubes 10 travel over switches 47 to collecting rail 48 at the end of which they are delivered by a lift 49 onto return rail section 37a whence they run under gravity to a lift 51 which delivers them to rail section 37b. Each lift is followed by an electrical safety switch 41, 50 or 52 actuating a time switch to arrest each preceding lift when the succeeding rail section is filled with stationary trolleys.

Title: Improvements in or relating to gas-blast electric circuit-breakers
IPC: H01H33/56
Filed: 1945-11-16
Abstract: 613,844. Gas-blast switches. NAAMLOOZE VENNOOTSCHAP FABRIEK VAN ELECTRISCHE APPARATEN VOORHEEN F. HAZEMEIJER & CO. Nov. 16, 1945, Nos. 30738 and 30739. Convention dates, April 15, 1943, and Feb. 12, 1944. [Class 38 (v)] In a pneumatically-actuated, gas-blast circuitbreaker, compressed air supplied via a conduit 14 and a connection-box 19 to the annularspace between insulating-tubes 1, 2, acts on a spring-biassed piston 5 which descends and opens the contacts 3, 4, the air-blast exhausting to atmosphere through the open end of the tube 2. The piston 5 also carries a contact-pin 8, slidable in the socket 9 of an end-cap 10 carrying a fixed isolator-contact 12, the movable-contact 13 being operable by a rod 21 and piston, the cylinder 20 of which opens into the box 19. As shown, a plurality of tubes may be arranged in a metal-tank 22 filled with an insulating-medium having a dielectricstrength greater than atmospheric-air, such as compressed-air, oil, or insulating-compound. When the insulating-medium is solid, the isolator must be movable inside the tubes, or alternatively the breaker contacts must themselves provide an isolating-gap. In a threephase totally-enclosed arrangement, Fig. 3, the annular-spaces 35 between insulating-tubes 49, 50 terminate in a connection-box 53, which is connected to a supply-tank 31 through an electromagnetic control-valve 32, and extensions 39 of the tubes 50 pass through metaltubes 38 which reinforce the tank 31. The movable isolator-contacts are carried by a bridge 43, and are operable by a rod 44 connected to a pneumatic-mechanism 45. Specifications 611,229 and 613,433 are referred to. The invention is also applicable to the switch described in " Electrical Engineering," dated September, 1940, on pages 504-506.
Patent GB-365076-A (GB)
Title: Improved process for dehydrating acetic acid
IPC: C07C51/487
Filed: 1930-10-14
Abstract: Acetic acid is dehydrated by forming nitrosyl sulphuric acid therein, for example by treating the acid with sulphur dioxide or trioxide and a suitable oxide of nitrogen.  As the oxide of nitrogen, nitric peroxide can be used, but it may be replaced by a mixture of nitric oxide and oxygen, or by concentrated nitric acid.  The sulphur dioxide may be developed in the solution from salts such as water soluble sulphites or bisulphites, or from organic sulphites such as ethyl sulphite.  The acetic acid may be separated by distillation, preferably under reduced pressure, from the gases dissolved therein and from the sulphuric acid formed, or it may be used without separation of the gases or sulphuric acid in acetylation processes, for example, in the acetylation of cellulose.  Cellulose (containing approximately 8 per cent of moisture) is treated with acetic acid, and nitric peroxide, sulphur dioxide and oxygen are introduced into the mass until the water is removed and crystals of nitrosyl sulphuric acid are formed.  The pretreated cellulose may then be acetylated, with or without the removal of the oxides of nitrogen and sulphur dioxide, since these gases together act as catalysts for the reaction.

Abstract: 656,763. Automatic mass flow control systems. NORMALAIR, Ltd., and MANN, F. C. D. Nov. 30, 1948, No. 31070. [Class 38 (iv)] [Also in Group XXXVII] Figs. 10, 11 show a mass flow controller embodying the electric switch of the invention. Arms 9a, 9b frictionally support the contact lever 13 on a pin 12 and are secured to a base 5 pivoted at 2 and connected by a pivot 6 and link 6<SP>1</SP>, 7<SP>1</SP> to a diaphragm 7. The contact 13 co-operates with U-shaped contacts 8a, 8b insulatedly carried by a part 4, also pivoted at 2, so that on movement of the diaphragm 7 one or the other of two circuits is closed to operate means causing a reversal of forces acting on the diaphragm. On movement of the diaphragm to the right with the contact lever 13 engaging the contact 8a, base 5 is rotated anticlockwise about pivot 2 until the other end of the lever 13 engages a side of the aperture in a bridge 14 secured to the arms 9a, 9b, further movement being resisted by the capsule pack 3 connected to the part 4 by a fork and link 5<SP>1</SP>. If the diaphragm then moves to the left the contact at 8a is immediately broken and on continued movement the contact 13 engages the contact 8b. The diaphragm 7 is spring-biassed to the left so that a pressure difference between its sides is necessary for balance; this pressure difference is required to be increased on decrease of pressure surrounding the capsule pack 3. On pressure decrease the pack 3 expands, rotating the part 4 counterclockwise, whereby the contacts 8b, 13 engage and a higher pressure difference between the sides of the diaphragm 7 is necessary for balance. Specification 655,328 is referred to.
